Hi, my problem is literally every harddisk i use eventually comes to a failure. It started before some time when i bought ASUS laptop (dont remember exactly which but it started i think it started with N5...;it had a Samsung HDD i think). After few moths there was an issue with hard disk so i sent the laptop to the service and they changed the hard disk. Everything was fine then but after some months it happen again. Same solution - changed hard disk. When it happened for third time i was really furious, because i thought it is laptops fault, so i ask to refund the laptop back. With the money i bought parts and made my own PC( was a year ago ). It is working fine till today, when HDD started to make strange noises( randomly making noise like when under high activity, sometimes it makes click sound - same it makes when i shut down computer), and also random drops in its speed(sometimes resulting in OS freezing for 2 secs) and a there is also SMART notice in the POST. I know that best solution is to backup and send for exchange as it is under warranty yet, but i think that it cannot be coincidence and i must be doing something wrong. Few things i can think of is temperature(that might have been the problem in the laptop but i dont think it is a case in PC as i sometimes checked the temperature), or maybe some software i use is causing it but i'am not sure if this is possible. I would be really thankful to any advice into future.
